COLLAR-BUTTON.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed November 2, 1905. Serial No. 285,624.

To all whom it may concern:

Be it known that I, GEORGE X. WVENDLING, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Collar-Buttons, of which the following is a specification.

My improvement relates to that class of buttons or studs in which a stud with a stem, head, and flange screws upon a flanged stem, and has for its object to prevent the parts from becoming detached, to Which end I construct the parts as fully set forth hereinafter, and as illustrated in the accompanying drawings, in which- 4 Figure 1 is an external view of a collar-button constructed in accordance with my improvement; Fig. 2, a view in section through the stud portion; Fig. 3, a view showing different parts detached; Fig. 4, a plan of the inner member of the button.

The button consists of three parts A, B, and C. The member A has a hollow threaded stem (Z with a flange c at the inner end. The member B has a threaded stem 6, adapted to the threaded socket of the member A and long enough to project beyond the latter. At the inner end of the stem e is a flange f, with serrations "L at the edge. The member C has a head I) and a stem a, which is socketed and threaded and adapted to the end of the stem 6.

In applying the button to a garment the stem e is passed through the buttonhole and the member A is screwed onto the said stem, which can be prevented from turning by gripping the edge of the flange f, the serrations afi'ording a proper hold for this purpose, so that the memberA can be turned to tightly clamp the garment between the parts 0 and f. After this is done the member C is screwed onto the projecting end of the stem 6, and when screwed tightly down it acts as a amnut to prevent the member A from turning, while the latter also acts as a jam-nut to prevent the member C from turning. This is especially important in view of the fact that in many cases the member 0 will have a socket for receiving a precious stone.

I claim A collar-button consisting of the members A, B, O, the member B having a threaded stem and disk with serrations at the edge, the member A having a hollow threaded stem and disk at one end, and the member C having a head and socketed stem with internal threads all substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE X. WENDLING.
